Can't get 5 GPUs working, only 4. (Asus z170 Pro Gaming Aura)

[dccomp]

Hi guys. About a month ago I bought these GPU's and components to start mining:

1x Asus Turbo GTX 1080 - 8Gb
2x Gigabyte Turbo GTX 1080 - 8Gb
2x MSI GTX 1050Ti - 4Gb

Motherboard Asus z170 Pro Gaming Aura
1x PSU EVGA 850 BQ.
CPU Intel Pentium G4400
SSD Kingston UV400 - 120 Gb
1x RAM Kingston HyperX Fury DDR4

Under Windows 10, I have succeeded in getting 4 GPU's to work fine. But I have not succeeded to run more than 4 GPU's. I've already check the raisers, Changing Gen1, Gen2, Gen3, Adding another PSU (Corsair CX 650M), Enable Above 4G decoding. And nothing seems to work.

- - ->> When I boot the rig with 5 GPU's, the Asus logo show up, then a black screen, and nothing else happen. <<- - -

I read in other post that the solution is to increase TOLUD to 3Gb instead of Auto. The thing is that I can't find the TOLUD option on Bios.

So, How can I change TOLUD on Asus z170 Pro Gaming Aura?.
If anyone could run more than 4 GPU's on this Motherboard, please share the settings.

Thanks in advance for your help!
Have a great day

 Change PCIE x4 slot to x2 in BIOS setting.. I guess it might work.

I'm on BIOS:
Advance Tab / System Agent (SA) Configuration/ DMI OPI Configuration.

But DMI option is Greyed out.

How can I change from x4 slot to x2 in BIOS?

how many risers are connected to one sata cable? I had issues when I connected 3 risers on one cable, now I have 2 riser per sata cable and it works fine

2 risers on one SATA cable

then try to disable 4g, boot into safe mode, use ddu to uninstall drivers, reboot to windows to install drivers, reboot to bios to enable 4g (or was it first enable 4g and then install drivers)

btw driver 17.2.2 suppport now all my 6 cards without moding the drivers

I'll try those steps.

The driver you are mentioning (17.2.2) is from the GPU's?, or the Motherboard?, or which component?.

The driver I'm currently using for the GPU's is 384.94, and works for both 1080's and 1050's ti GPU's.
The current Motherboard driver is 3401.

Please check in Advanced--> Onboard Device Configuration--> PCIEX16_ slot Bandwidth..  and see if x4 mode, x2 mode and auto are in options.

if its present.. put that in x2 mode and see if 5th gpu works..

I don't see that option. I see these options:

I only see PCIEX16 info on Tool Tab. Here are some images.

The raisers are plugged in:
PCIEX16_1 = Asus Turbo GTX 1080 - 8Gb
PCIEX1_1 = Gigabyte Turbo GTX 1080 - 8Gb
PCIEX1_2 = Gigabyte Turbo GTX 1080 - 8Gb
PCIEX16_3 = MSI GTX 1050Ti - 4Gb

Thanks for your reply. I've already checked the video and follow those steps. But still not working. Only 4 GPU's.

What version of Bios do you have?

I have Ver. 3401

Some motherboards disable certain PCIe lanes if you use the 16x PCIe slot on the motherboard. Check if yours isn't perhaps doing this.
